Obtaining socket stats for all other tests

[hrishikeshathalye]

Can the code be changed in some way to obtain socket stats for tests other than tcp1up using the same SsRunner? All the other runners inherit from ProcessRunner, so my guess is adding the code to detect the SOCKET_STATS option there will be the way to do it? Something similar to the below lines of code in NetperfdemoRunner, but that can work for tests other than TCP_STREAM?

if args['test'] == 'TCP_STREAM' and self.settings.SOCKET_STATS:
  self.add_child(SsRunner,
                 exclude_ports=(args['control_port'],),
                 delay=self.delay,
                 remote_host=None,
                 host=self.remote_host or 'localhost',
                 interval=args['interval'],
                 length=self.length,
                 target=self.host,
                 ip_version=args['ip_version'])

What are you trying to achieve? The socket stats are captured from the output of 'ss', which only carries the extended stats for TCP sockets...

I am trying to obtain stats for http-1up with a single worker and would like to have the stats for the underlying TCP socket that it uses

Right, so while that's doable, the socket stats won't show you that much useful information for incoming flows - this is also the reason why it's only enabled for TCP_STREAM flows in netperf.

As for adding the capability, I think the way to go about it would be to move the add_child() call you quoted above into a helper function in ProcessRunner, and have the child runners call that if the test they're running is compatible with socket stats (i.e., TCP_STREAM tests for netperf).
